and sperm production and fat body depletion connnnences. Adrenal gland 

 volume increases to reach a maximum during the summer, which initiates 

 intraspecific aggressive and sexual behavior. The breeding season ends 

 in late July with opposite responses of the above attributes.

 bodies of the lizard, Cnemidophorus tigris, prior to hibernation. COM- 

 PARATIVE BIOCHEMISTRY AND PHYSIOLOGY ^^lOB): 661-66^. 



Lizards were collected in late August from El Paso County, Texas. 

 Females had a larger mean fat body weight. Fat bodies contained the 

 highest percentage of lipids (66-97), while liver and carcass ranges 

 were lO-'fS and 2-1^, respectively. A list of fatty acids identified (8 

 total) is given.

 yses and the origin and relative age of parthenogenetic lizards (genus 

 Cnemidophorus ). SCIENCE 203: 12^7-12^9. 



Analyses of mitochondrial DNA's (which are inherited maternally) 

 and their endonuclease digestion products confirm the hybrid origins of 

 Cnemidophorus neomexicanus and diploid C. tesselatus . C_. tigris mar - 

 moratus is indicated as the maternal parent species in both cases. The 

 data imply that these two parthenospecies are younger than some races of 

 Cnemidophorus tigris .

G- and C-banding of both meiosis and mitosis in Cnemidophorus 

 tigris show that the X and Y chromosomes are homologous but do not cross 

 over in the centromere region, where they differ in centric position and 

 heterochromatin.

Cnemidophorus tigris populations were markedly depressed in gra- 

 zed areas in contrast to ungrazed ones. Both lizard numbers and lizard 

 biomass were down in ORV use areas compared to non-ORV use areas.
